Yuav ua li cas kom txhob lo lo ntxhuav

Cov txhob lo lo ntxhuav muaj ob lub monofilaments, lub cev tseem ceeb ntawm cov ntaub so ntswg, thiab txheej txheej yog qhwv nrog sericin. Feem ntau ntawm cov pigments, roj, waxes thiab inorganic ntsev muaj nyob rau hauv sericin. Cov impurities no muaj kev cuam tshuam zoo rau kev luam ntawv thiab dyeing, yog li lawv yuav tsum tau muab tshem tawm ua ntej dyeing. Hauv kev xyaum mus sij hawm ntev, tib neeg tau paub txog cov yam ntxwv ntawm sericin uas yooj yim yaj hauv dej kub nyob rau hauv qhov kev txiav txim ntawm cov tshuaj siv tshuaj lossis cov enzymes, thiab ua kom zoo dua qhov tsis muaj zog ntawm sericin kom muab cov lo lo ntxhuav nyoos los yog cov lo lo ntxhuav nyoos rau hauv xab npum (los yog cov tshuaj tua hluavtaws. ) thiab cov tshuaj tov ntawm dej qab zib tshauv (sodium carbonate) yog rhuab, thiab cov sericin yog rhuab thiab ces hydrolyzed. Tom qab kev ua kom zoo li no, cov tshuaj sericin raug tshem tawm thiab cov protein ntau yog khaws cia, thiab cov impurities xws li pigments, fats, thiab waxes raug tshem tawm, thiaj li tau txais cov khoom lo lo ntxhuav nrog cov xim dawb. Degumming kuj yog hu ua refining, thiab cov ntaub ntawv nyoos tom qab degumming yog hu ua cov ntaub qhwv. Lub degree ntawm raw cov ntaub so ntswg degumming yuav tsum tau txiav txim raws li ntau lawm yuav tsum tau.
